We want to take a train from Zurich to Bregenz, Austria (to pick up an Austrian car) I noticed the the route is better on Omio. What is that and is it reliable?
Can we buy tickets once we arrive or do we need to pre-purchase?
I have an injury so the whole trip is not certain. I already purchased train tickets that we won't use and are non-refundable so I don't want to do that again, unless they are cheap.
